What is radiation hazard

Radiation exposure in Austria

Natural radiation exposure

The average radiation dose from natural radiation sources is around 2.8 mSv per inhabitant and year. Slightly more than half of this is due to the radioactive noble gas radon, the rest to cosmic and terrestrial radiation and the ingestion of natural radioactive substances with food.

However, natural radiation exposure is subject to considerable fluctuations, mainly due to different radon levels. In certain areas with special geological conditions, the radiation exposure from inhalation of radon is significantly higher than the national average. You can find more information about radon here.

Civilization radiation exposure

The radiation exposure caused by civilization averages around 1.4 mSv per inhabitant and year and is mainly due to the use of radioactive substances and ionizing radiation in medicine, especially in X-ray diagnostics.

At less than 0.01 mSv per year, the radiation exposure caused by the Chernobyl reactor accident in 1986 and the aboveground nuclear weapons tests in the 1950s and 1960s is comparatively very low.
